Embodiment

The invention provides locking mechanism with substance locking mode and double locking pattern.The substance locking mode relates to the motion of movable member, and for example lock finger is around the rotation of axle.The double locking mode response is in taking place along moving of axle.Locking component can not be disengaged in the double locking pattern.Under the situation that each member engages with the substance locking mode and the someone attempts front shroud is pried open from casing simultaneously, the double locking pattern takes place automatically, has therefore hindered the trial of evading locking mechanism.

Fig. 1 shows at normal condition (upper left) down and the vertical type machine AP1 of former frame 11 when being pried open (upper right) with formation gap 15 from computer housing 13.Computer A P1 provides and has been used for frame 11 is fixed to locking mechanism 16 on the casing 13.Gap 15 can be used as inlet, can insert instrument to attempt leaving fixedly latch hook 19 or other fixed component is disengaged locking mechanism 16 by pivot lock finger 17 or other movable member by this inlet.

Locking mechanism 16 is designed to stop and removes frame 11 by this way.The motion (finger 17 engages with hook 19 simultaneously) that frame 11 leaves computer housing 13 forces locking mechanism 16 to enter double locking pattern 23 (bottom right of Fig. 1 and centre) from substance locking mode 21 (lower-left of Fig. 1).In substance locking mode 21, finger 17 and hook 19 engage so that frame 11 is locked into casing 13.In this pattern, finger 17 can be pivoted, and for example is inserted into key (shown in Figure 2) in the locking mechanism 16 by use, so that finger 17 is disengaged from hook 19, therefore allows frame 11 is removed from casing 13.In double locking pattern 23, finger 17 can not be pivoted to and break away from and the engaging of hook 19.

More specifically, frame 11 pried open from casing 13 make the teat 27 of hook 19 be inserted into the groove 29 of finger 17, realize double locking pattern 23 whereby.In the double locking pattern, finger 17 is locked on the hook 19, thereby makes finger 17 not to be pivoted to break away from and the engaging of hook 19.

The top of Fig. 2 shows finger 17 and the hook 19 under substance locking mode 21.Substance locking mode 21 can be realized in the following way: key 24 is inserted in the locking mechanism 16, and the key 24 that turns clockwise then with finger 17 is pivoted (for example, shown in curved arrow 31) to being in engagement state with hook 19.On the contrary, from substance locking mode 21 (Fig. 1), key 24 can be rotated counterclockwise, and is disengaged (entering non-locking pattern whereby) so that finger 17 is pivoted to hook 19, thereby makes and frame 11 can be removed from casing 13.Under double locking pattern 23 (Fig. 1), stop finger 17 pivots and correspondingly will stop key 24 to rotate.Certainly, when finger 17 did not engage with hook 19, two locking modes all were not activated, and prized action and can not make the double locking pattern 23 that enters.

The lower part of Fig. 2 shows finger 17 and hook 19 (each other in the relation of decomposing, finger is rotated counterclockwise 90 degree and enters unlocked position) individually.Hook 19 comprises the hook portion 33 that extends forward, the attachment part 35 that extends back and middle lateral part 37.Attachment part 35 comprises two holes 39, and these two holes 39 are used for being attached to side cover plate 41 by rivet 42, as shown in Figure 3.For computer A P1, when side cover plate 41 was installed on the casing 13, hook 19 was couple to casing 13 rigidly, as shown in Figure 4.In other embodiments, fixedly locked member can directly be attached on the casing; But, hook 19 being attached to side cover plate 41 allows a locking mechanism that plate 41 and frame 11 both lockings are gone up in place.Extend along the antetheca 43 (shown in Fig. 2) of casing 13 middle lateral part 37.

As shown in Figure 2, hook portion 33 comprises groove 45, and when frame 11 was locked on plate 41 and the casing 13, groove 45 was the positions that engage with finger 17.Groove 45 defines forward recess wall 47 and recurve cell wall 49.The teat 27 that uses in double locking pattern 23 is limited in the forward recess wall 47.

Finger 17 comprises the finger part 51 that extends radially outwardly, the holder part 53 that extends radially inwardly and axially extended center section 55.Center section 55 and axle 57 extend between finger part 51 and holder part 53 abreast, and key 24 rotates around this axle 57 in the key hole 59 that is inserted into locking mechanism 16 time, and finger 17 is around these axle 57 pivots.Holder part 53 comprises elongated groove 67.As can seeing best among Fig. 5, the rotatable shaft 69 of locking mechanism 16 extends through groove 67, and keeps going up in position between
